Every bullet has limitations and shots need to be made according the limitations of the bullet. The key is knowing the limitations, making the shot required, and passing up those shots that the bullet is unsuitable for.
Most of us would be unwilling to live with the limitations of a 22cf when hunting bears, but that does not mean a 22cf is incapable of reliably killing a bear.
Yes, I agree with the theoretic fact that a .22 centerfire (caliber) will kill a brown/grizzly bear. However, I question the choice, as opposed to the happenstance circumstance.
As someone whose (thus far) been responsible for the killing of more than 140 of the beasts, I would definitely question the choice of that caliber over something larger.
But, I would agree with the theory of its (.22 centerfire) capability on brown/grizzly bear when used in controlled (predictable) situations or possibly even a happenstance (sheer luck) chance.
